ANTI-THIEF ELECTRONIC DEVICE AND METHOD THEREOF
First Claim
1. An anti-thief electronic device capable of confirming respective existing statuses of a plurality of apparatuses coupled thereto, the anti-thief electronic device comprising:
- a first table, storing respective initial existing statuses of the apparatuses coupled to the anti-thief electronic device as regular existing statuses;
a second table, storing respective existing statuses of the apparatuses periodically;
a micro control unit, periodically comparing the second table with the first table to confirm whether the respective existing statuses of the apparatuses are changed or not; and
an alert device, generating an alert if the respective existing statuses of the apparatuses are changed.

Abstract
An anti-thief electronic device capable of confirming respective existing statuses of a plurality of apparatuses coupled thereto and method thereof is disclosed. The anti-thief electronic device includes a first table, a second table, a micro control unit and an alert device. The first table stores respective initial existing statuses of the apparatuses coupled to the anti-thief electronic device as regular existing statuses. The second table stores respective existing statuses of the apparatuses periodically. The micro control unit periodically compares the second table with the first table to confirm whether the respective existing statuses of the apparatuses are changed or not. The alert device generates an alert if the respective existing statuses of the apparatuses are changed. Specifically, the micro control unit periodically queries an extended display identification data from the display for detecting the removal of the display.
